Abstract: The aim of the paper is to prevent collision between trains, obstacles on track and human negligence. Railway is the most popular and convenient transportation system in the world. Train is widely used for comfortable and safe journey in a affordable fare. People from different occupation can effort it. But consistently, the train is facing unpredictable circumstances in travelling because of wrong signal, erroneous track switching, unmanned level crossing etc. for which collision have been resulted. As a result, lot of damages and harm has been done in financial sector with lot of fatalities which affect our country's development progress. But we can avert this unpredictable collision and take prevention from the accident by using the collision detection technology which can be made by ultrasonic sensor, arduino micro controller radar module, motor driver unit with a special enclosed system. By using this technology we can detect the obstacles, train on same track and cautiously slow down the speed by automatically applying the air brake to stop the train before the collision takes place.
